To all whom it may concern:

Be it known that I, GUSTAV Ft'iasr, merchant, a subject of the King ofAustria-Hungary, and a resident of Pozsony, in the'Empire ofAustria-Hungary, have invented certain new and useful Improvements inTime- Registers for Telephones, of which the following is a secification.

In the well-known recorders of the time of talking when using tele honeseither the number of times the telephone is used or the total time ofusethat is to say, the sum of the times occupied in talking andlistening are recorded. According to this invention, however, only thetime is recorded or registered during which the user is actually engagedin talking or usin the transmitter, the time during which he cordedthatis to say, onl the time of use of the transmitter and not t at of thereceiver is recorded. This is effected, according to this invention, byenabling the user to break the circuit of the transmitter at any desiredmoment inde endently of the circuit of the receiver, so t at on thetransmitter-circuit being broken the receiver or receivers of theinstrument in question can be used alone. The closing of thetransmitter-circuit is effected b means of a device arranged so that apart 0% it projects outside the casing of the instrument, the saiddevice enabling the transmitter-circuit to be broken by the user at anydesired moment, the switch affecting the switching-in of the transmitterat the same time operating the driving and 100 device of a time recorderor counter in such manner that the closing of the transmittercircuitsimultaneously releases the clockwork, the breaking oithetransmitter-circuit stopping the same. Owing to this arrangement, onlythe time during which the transmitter of the instrument is used isregistered.

As far as the spirit of this invention is concerned the kind of thetelephone or time-recorder used is immaterial, as is the manner in whichthe interrupter for the transmittercircuit is switched in and out andconnected to the ratchet or locking device of the counting apparatus.

construction of an apparatus according illustrated, b way of example, inthe accompanying awings, in Whic Figure 1 shows a construction of theapparatus in its position of rest in vertical lon tens not being re-'clockwork mechanism w tudinal section. Fig. 2 is a back view. Fig. l

3 shows for talking. of the apparatus. Fig. 5 shows another constructionof the apparatus.

he spring-contacts 1 and 2, Fig. 1, have the tendency to keep thetransmitter-circuit broken. The closing of these contacts is effected bya rod 3, arran ed in the interior of the instrument-casing, t e risingof said rod causin the contact-springs l and 2 to be presse a ainst eachother. The movement of the ro is effected by. a lever 28, which ishinged to it and projects outside the instrument throug a slot in thecasing thereof, a spring 12 acting on the said lever to keep it in itsnormal position, with the rod 3 depressed. The rod 3 also controls thetimerecorder 6, which may be a chain of dialthe device in the positionready 'wheels, as illustrated in Fig. 2, or any other suitable means, insuch a way that when said rod 3 is raisedthat is, when the handle of thelever 28 is depressedthe time-recording mechanism is released, whilewhen the leverhandle is released it is locked again, as will behereinafter more fully described. In the construction lustrated themovement of the lever 28that is, of the rod 3is also Fig. 4 is a diagramof connections.

utilized for winding up the motor-train or hich operates the registeringmeans 6. This arm is provided with a pawl 45, engaging with aratchetwheel 46 of the clockwork mechanism, and rests on a'roller 8,supported by one arm of a puilvoted lever 7, the other arm of whichisged to the rod 3. The lever 7 is acted upon by the sprin 11, which tendsto raise the lever 9, with th position by means of the Callin up,switching in of the receivers and of t e transmitter, as well as thesimultaneously switchin out of the bell, may be effected in the usuamanner, for as far as the invention is concerned the only importantpoint is that besides these well-known devices there should be arrangeda special switch 1 2 for the transmitter-circuit, by means of which thetransmittercircuit could be broken independently of the receiver-circuitat any desired moment by the user, while immediately thetransmitter-circuit is closed by the said contacts 1 2 mechanism in atime-recorder is released and the length of'time for which thetransmitter-circuit is closed is recorded.

Whenever it is desired to use the transmitroller 8.

e weight 10, into highest that the latter can operate the ratchet-wheel45, and thus drive the clockwork which is connected with the spindle ofthe said wheel.

As soon, however, as the lever 28 is released and the contact at 1 and 2thus broken the roller 8 raises the arm 9 and the time-recorder isstopped. I

The time during which the clockwork acts that is to say, the time whichthe weighted arm 9 takes to reach its lowest position-is preferablydetermined so as to correspond with the ordinary duration of aconversation. Should, however, the clockwork stop before the end of theconversation, the free end of the arm 9 in its lowest position operatesa contact-spring 5, and thus breaks the contact between 4 and 5. Thecontacts 4 and 5 are in the transmitter circuit, (see Figs- 1,) so thatwhen this contact is broken the transmittercircuit is broken. Shouldthis ha pen, it will be sufiicient merely to release t e ever 28 for onemoment and then depress it again, whereupon the weighted arm will beraised and the clockwork start anew.

In order that both receivers may be simultaneously used and at the sametime the hands may be left free for moving the lever 28, the receivers13 are preferably arranged on arms 14, secured to the ends of a spindle15, passing transverselythrough the casing.

of the instrument. When the instrument 1s not in use, the arms 14 are inthe position shown in Fi s. 1 and 2, the two receivers adjoining theIateral walls of the casing of the instrument. In this position thecurrent from the line L, Fig. 4, passes through the bell-circuit 30,contact-springs 2,0 21, through .the wire 48, and contacts 19 18 to theline L,

since the contacts 1 2 25 31 and 26 32 are broken. If, however, it isdesired to use the apparatus, the arms 14 are turned forward, whichbrings the receivers into the position of use, Fig. 3. ment the spindle15 effects all the switching required-that is to say, the in 16 on thesegment 24, Fig. 1, releases t e spring 18, which normallyshort-circuits the armature 22 of the bell-inductor with the contact-pin19, and at the same time the toothed segment 24 on the spindle throu hthe pinion 23 causes the armature 22 of t e bell-inductor to turn,thereby calling up the other user. At

the end of the path through which the spin-' dle 15 turns the pin 17 onthe segment separates the contact-spring 21 from the spring 20, Fig. 3,and thus breaks the contact which held the bell switched into theline-circuit, thus cutting out the bell. At the same time the contacts25 26, mounted on and electrically insulated from the spindle 15, Fig.2,

During this turning move-- come into engagement with the contactsprings31 32. These latter switch both the instruments into the line-circuit,the transmitter-circuit remaining, however, 0 en until the lever 28 isdepressed. During t e movement of the arms 14 before the pin 17 breakscontact at 20 21 the circuit from L is closed through 30, 20, 21, 22,andL, while in the extreme position of the arms 14 (shown in Fig. 3) thecurrent passes from L through the secondary winding of theinduction-coil 33, contacts 32 26, the receivers 13 13, contacts 25 31,and into the line L. When, however, by depressing the lever 28 contactis made at 1 2', the circuit of the battery B is closed through theprimary winding of the induction-coil 33 and the transmitter 29. Thespindle 15 is also provided with a projection 27, Figs. 1 and 3, whichprevents the lever 28 from moving when the instrument is in theposition'of rest, Fig. 1. If, however, it be desired to keep to theusual free handling of the receivers and also to render it possible touse both, a press-button 42 may be arran ed on one of the handles of thereceivers, as iagrammatically shown in Fig. 5. In that construction thetransmission of the movement of the press-button to the switch 1 2 inthe interior of the instrument and to the ratchet device of thetime-recorder is effected by electrical means, such as an-electromagnet34. This electromagnet is preferably sup lied with current from thesource of current of the transmitter and is switched in parallel withthe transmitter or microphone. So long as the receiver 31 hangs on thehook 36 the circuit of the transmitter is broken, .since the arm 37 ofthe hook 36 holds the armature of the electromagnet forming one contact1 away from the stud 2, and, on the other hand, the circuit of theelectromagnet 34 is broken at 37 35. When the receiver is lifted 05 thehook 36, the latter effects in the well-known manner the necessarycontact make and break, the arm 37 closing the electroma net-circuit bymeans of contact 35, so

that t e electromagnet becomes operative and attracts its armature.Owing to this, the transmitter-circuit inspite of the arm 37 havingreleased the armature remains broken at 1 2, so that only the receiverscan be used, the transmitter-circuit being broken. When it is desired touse the latter, the knob 42 on one of the receivers is depressed, the,electromagnet-circuit being broken at 49 50, all current thus being cutoff from the said electromagnet 34, whose armature is then released andthe contact between 1 and 2 closed. The movements of the armature aretransmitted to the ratchet device of the time-recorder in any desiredmanner-as, for instance, in the drawings, by the hook 43 secured to thearmature and engaging with the balance 44 of the time-recorder-so thatthe making of the contact between 1 and 2 at the sametime brings aboutthe release of the clockwork.

The wires 51 are arranged in the cable leading to the receiver. If it isdesired to arrange pressure-knobs 42 on both receivers, the switches 4950 on both the telephones must be arranged in series with each other.

I claim as my invention- 1. A time-register for tele hones, providedwith means for registering t e time of use of the transmitterindependently of the receiver.

2. A time-register for telephones, comprising a motor-train mechanism, atransmitter and means to permit both to act together and a receiveradapted to be used independently of the mechanism and transmitter.

3. A time-register for telephones, comprising a motor-train mechanism, atransmitter and transmitter-circuit, and manually-operated means forplacing said mechanism and transmitter into operative position and areceiver independent of the mechanism and transmitter.

41..
